I almost bought a Rain Forest Green boxster also, if I ever factory order a porsche (whether its another boxster or a GT2) i'm getting it in Rain Forest Green Metallic, I don't care if I have to wait, I just think that color is very unique.
I went new also. '04 with 17 miles on the clock when I picked it up. I had to have a few things such as glass rear window, sport seats, Carrera lightweights, etc. and at the time there weren't many used '03 cars for sale with those specific options (nor at very good prices).
